摘要：
A method of creating a thermochromic artificial blood vessel includes physically cross-linking a polyvinyl alcohol solution in a mold shaped to mimic a blood vessel to create an artificial blood vessel. The artificial tissue is then chemically cross-linked with a solution including a chemical cross-linking reagent. A coagulation solution is then applied to the artificial blood vessel to both inhibit the chemical cross-linking and promote physical cross-linking of the artificial blood vessel. The artificial blood vessel can be used to test an ablation catheter. The vessel, when heated by the ablation catheter, changes color and/or transparency at locations where the temperature of artificial blood vessel increases.
